VB.NET Question - .NET Framework

Ryan Smith

I have an app that I need to build and it consists of 5 distinct sections
with many subitems for each. I am going to layout the software in a way
similar to MS Money.

I want to autogenerate the left hand navigation from an XML file and that is
not hard. What I can't figure out is how to encapsulate each portion of the
software in a separate .dll and then call that form from the dll and display
it to the user. This would make it ideal for future updates and additions.

Any feedback would be greatly appreciated!

You will want each section to be in it's own project. Set all each project
to a class library type. If they are all in the same solution you can then
reference the new classes just as if they were all in the same project like
you are use to now.

Let me know if you need me to go into more detail.

I would suggest that you look into Reflection.

The XML file lists an initial set of plug-in modules for your application.
You use Reflection to load each one.
Your main app defines a set of interfaces that each plug-in must conform to.
One of the interfaces provides your main app with a mechanism for building
the navigation tree (e.g. each plug in adds itself to the navigation... you
don't add it). This means that the plug-ins themselves register for the
event that will occur when their item is clicked.

A good start, using VB.Net, is in this article.

The easy way to turn off automatic updates for Windows 10/11

In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
